ALBERT OROSSER, OF HARTLEY, IOWA.

FOUR-HORSE EVENER.

SPECIFICATION forming part of Letters Patent No. 692,987, dated February1 1, 1902.

Application filed July 23, 1901. Serial No. 69,437. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT CRossnR, a citizen of the United States,residing at Hartley, in the county of OBrien and State of Iowa, haveinvented certain new and useful Improvements in Four-Horse Eveners; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to certain new and useful improvements indraft-equalizers,and particularly to that class known as four-horseeveners.

This invention has for its object to overcome the side draft common toall agricultural implements to which the horses are attachedunevenly-that is to say, the drafthorses are so disposed with relationto the draft-rod that more horses are located on one side thereof thanon the other side. Ordinarily this arrangement of the horses gives themachine the tendency to deviate from a straight course by reason of theunequal draft on the opposite sides of the draft-bar, and it is toobviate this undesirable feature that my invention is designed. I attainthis object by rigidly mounting a cross-bar near the end of thedraft-bar in such a position as to stand at right angles to thedraft-bar, with its greater part on one side thereof, where it issecurely held in position by braces. Traveling through a channel of thecross-bar and mounted on suitable pulleys therein is a chain, to eachend of which is a doubletree carrying a pair of singletrees, thesiugletrees of one pair being located on opposite sides of thedraft-bar, so that in all there are three singletrees on one side of thedraft-bar and only one on the other side thereof. By this arrangementthe draft of each pair of horses is equalized by the draft of the otherpair instead of there being three times the amount of draft on one ltails of construction and combination of elements, to be clearlydescribed in the following specification and fully set forth in theclaims.

Referring to the accompanying drawings, forming a part of thisapplication, and in which like characters of reference indicate similarparts throughout the several views,

Figure l is a plan view of my improved four horse evener as applied to amowing-machine, of which a mere fragment is here shown. Fig. 2 is a sideelevation thereof. Fig. 3 is a front elevation of the cross-bar with thedraft-bar in section and taken on the line 3 3 of Fig. 1, and Fig. 4 isa perspective view of the brace.

In the drawings, A represents a draft-bar of ordinary constructionconnected at its rear end to a mowing-machine B in the usual yoke C.

To the rear end of the draft-bar A, in front of machine B, is rigidlyattached a cross-bar D at a point about three-fourths of its length andsecurely held in position, which is at right angles to the draft-bar, bya brace-rod E, extending from the long end of the crossbar D rearwardacross the draft-bar to the machine proper, and a brace 'F, connected tothe short end of the cross-bar D and extending forward and connected tothe draft-barA. In detail the brace F consists of a plate of sheet metalcomprising a straight arm f, with its end located between the draft-barA and cross-bar D and provided with apertures f to receive theconnecting-bolts joining said draft-bar and cross-bar. The other end ofarmf is apertured at f to receive a bolt in the short end of thecross-bar D, and at this end there merges with the arm f a second arm f,which lies in the same plane with, but at an acute angle to, the arm fand has its extremity f bent downward at right angles to engage the farside of the draft-bar A, to which it is bolted, as is also this end ofarm f.

Along the front edge of the cross-bar D is a channel G, in each end ofwhich isjournaled a pulley H, around which and. through the channelextends a chain Lhaving attached at each end a doubletree J, carryingpairs of singletrees K, the pair of singletrees at the manner and havingat its forward end a neckshort end of the cross-bar being located onopposite sides of the draft-bar, so that there will be three horseslocated on one side of said draft-bar and one horse on the other sidethereof. As some mac hiues have greater side draft than others, I preferto provide the short end of the cross-bar D with a number ofperforations L, so that the pulley at this end may be adjusted to varyits distance from the draft-bar and so compensate for such differences.

From the above description it will be seen that I efiectnally overcomeall side draft in machines of this order and provide a very simple andsubstantial construction which will be easy to manufacture and strongand durable in use.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows:

1. In a device of the character described, a draft-bar, a cross-barrigidly secured thereto, with a greater length on one side of thedraftbar than-on the other, a brace-rod connecting the long end of thecross-bar with the machine, a brace connecting the short end of thecross-bar with the draft-bar, a channel in the front edge of thedraft-bar, a pulley mounted in each end thereof, a chain extendingaround the pulleys and through the channel, and means on the end of thechain to which horses may be attached, substantially as described.

2. In a device of the character described, a draft-bar, a cross-barrigidly secured thereto with a greater length on one side of thedraftbar than on the other, a brace-rod extending from the long end ofcross-bar rearward beneath the draft-bar and connected to the machine,an angular brace extending from shortend of the cross-bar forward to thedraftbar with its end bent thereover and secured thereto, a channel inthe front edge of the cross-bar, a pulley mounted in each end there of,the pulley at the short end of the crossbar being adjustable withrelation to the draft-bar, a chain extending around the pulleys andthrough the channel and means on the ends of the chain to which horsesmay be attached, substantially as described.

In testimony whereof I affix my signatu re in presence of two witnesses.

ALBERT CROSSER.
